A5E32337685 SITRANS LR260 (PROFIBUS PA) – OPERATING INSTRUCTIONS Page 67
mmmmm
Parameters
2.3.1.1. Target Mode
Used to request an operating mode from the Function Block.
Allows you to put the SITRANS LR260 into Out of Service Mode and then
reset it to Automatic Mode.
Manual Mode is used in conjunction with Simulation. See
Simulation
on
page 46. It should be used only with SIMATIC PDM in order to benefit from
all the features available.
2.3.1.2. Label
User defined label
2.3.1.3. Unit
Engineering unit to be displayed with the output value
2.3.1.4. Filter Time Constant (FILTER TIME CONST)
The time constant for the damping filter. (See Damping on page 106
for
more detail.
)
The engineering unit is always in seconds. (This is an
exponential filter: when a change occurs at the input, the output will be at
63.2% of the change in one time constant, and will be at full change after 5
time constants.)
2.3.1.5. Channel
Used to select between the different Level Transducer Block outputs.
When volume is not supported, the Primary Variable (Level/Volume) will
have alternate functionality. It is possible to configure the Transducer
Block outputs so that PV/SV1 is not always a level output.
2.3.1.6. Batch Information (BATCH INFO)
These 4 parameters are intended to be used in Batch Applications
conforming to IEC 61512 Part 1 (ISA S88). Other applications do not require
these values, which are only stored in the Function Block.
